DETROIT (WWJ/AP) – An online effort to raise $50,000 for additional security at Detroit’s Heidelberg Project following a series of fires has exceeded its goal.

The fundraising drive, which ended Friday, raised a total of $54, 280. The money will be used to help implement security measures at the outdoor art installation, including surveillance cameras, increased lighting and a nightly mobile patrol.

Founder and artistic director Tyree Guyton and his compatriots vow to carry on, make more art and overcome the assault on his vision, yet worry threatens the whimsy as the fires snuff out building after building.

Now, piles of rubble alternate with the three remaining house installations within the two-block area on the city’s east side that’s become famous over the years for the exhibition featuring shoes, clocks, vinyl records, stuffed animals and other found or discarded objects.

The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives has been investigating along with Detroit authorities. ATF spokesman Donald Dawkins said investigators have interviewed several people — some more than once — but he said there is no one yet that officials consider a suspect or person of interest.

El Don Parham, chief of the Detroit Fire Department’s arson unit, said it’s far too early to speculate on a motive but believes that “someone is pinpointing” the Heidelberg Project.

“That makes it a greater concern for us — that someone is targeting this area,” he said.

Guyton, often out working or cleaning up the site, has declined requests to speak with reporters. He told The Detroit News recently that he was “following the advice of the Greek philosopher Socrates: Be quiet and listen.”

In late November during Heidelberg’s annual fall fundraiser, Guyton said he would “do it bigger and do it better than before” but needed financial help.

The project has muscled its way into cultural and public acceptance despite rocky beginnings. It was originally viewed as an eyesore by city officials, who demolished parts of it at various points in the 1990s, but it now attracts tourists from across the country and globe and gets a seal of approval from the Detroit Metro Convention & Visitors Bureau.

It’s not lost on supporters that the Heidelberg — launched in response to urban decay — is fighting to save itself as the Detroit Institute of Arts fends off creditors eyeing its collection in Detroit’s bankruptcy proceedings. Detroit emergency manager Kevyn Orr hasn’t said whether he will sell art as part of any restructuring plan.

Judy Bradley, secretary at the nearby Jefferson Avenue Presbyterian Church, said she first visited Heidelberg in the late 1980s and has taken out-of-town family and friends many times since. She has wondered if Guyton has enemies, if an individual or group perceives the artwork as “ostentatious” or people just “want to get rid of it.”

“I think that what he is doing is just being proactive to the city and giving back. I think that’s what it’s all about,” she said. “It’s just a shame.”
